Room 8's Gravity Experiment

Gravity Experiment

Yesterday we conducted a gravity experiment to see which items would hit the ground first.

This were the items we needed:

• Ping Pong Ball x1
  
• Pin x1
• Paper x1 (A4)
• Feather x1
• Marble x1
• Pencil x1
• Rubber x1

This was the table we made as part of our investigation. First we had to guess/estimate which we thought would hit the ground first. Afterwards we had to test which objects would hit the ground first, we had to look at the table to see what object we were going to drop and what was going to compete against it. Once we had dropped the objects at least three times we wrote down which hit the ground first in most occassions. We did this until we have dropped every object that was on the table

Object Dropped		Which hit the ground first?	Which actually hit the ground first?
Marble	Ping pong ball	Marble	marble
Rubber	Paper Clip	rubber	rubber
Marble	Pencil	marble	Same time
Flat Paper	Feather	feather	paper
Crumbled Paper	Feather	crumbled paper	crumbled paper
Feather	Paper Clip	paper clip	paper clip

This is what we would’ve looked like:

I Know What It Was

I Know What It Was

They said it was just

an owl in the tree

but they didn’t

fool me!

I saw teeth

not a beak,

red eyes

not gold,

I won’t be told

it was only fluff and feathers

round its throat;

it was a collar

an those weren’t wings

but silky folds

of a black, black cloak

That was no

Too - wit, too woo

I heard

it was

I’ll get you - ou!

Chemical Mixtures

Ko te Rahina 16 o te Mahuru o tenei ra

WALHT: Observe and report on the chemical reaction that occur when combining substances together.

Experiment - Mix carbonates and bases to acids and record the reaction that follows

Combination	Hypothesis	Reaction
Lemon Juice - Citric Acid	We predicted that the colour would change or lose it’s original colour	The lemon juice colour faded after being mixed into the citric acid which then after solidified.
Raro - Vinegar	We predicted that the vinegar’s colour would over power the Raro’s distinct orange colour.	The reaction turned the vinegar into orange coloured liquid
Vinegar - Tartaric Acid	We predicted that the vinegar would turn the tartaric acid into a black liquid like it’s original colour black.	It looked like coke and solidified.
Baking Soda - Vinegar	We didn’t really predict because we have done this many times.	It rose and foamed up due to the chemical reaction.
